How This Calculator Works
This tool estimates the total lumens and approximate wattage needed for adequate lighting:
- Lumens: Measures the total visible light output.
- Foot-Candle (fc): Measures light intensity on a surface.
- Lumen Calculation: Uses the formula:
Total Lumens = Room Area (Length × Width) × Recommended Foot-Candles - The recommended foot-candles depend on the selected 'Room Type'.
- Wattage Estimation: Converts the total lumens to approximate watts for different bulb types (LED, Halogen, Incandescent) using average efficiency ratios (Lumens per Watt). This helps compare energy consumption.
Disclaimer: Estimation Only
This calculator provides general estimates. Actual lighting and wattage needs can vary based on ceiling height, colors, fixture types, specific bulb efficiency, and personal preference. Always check bulb packaging for actual lumen output and wattage. Consulting a lighting professional is recommended for precise design.
